Growing turnips in Wisconsin can be a rewarding experience for gardeners looking to cultivate a nutritious and versatile root vegetable. With the right techniques and understanding of the local climate, you can produce a bountiful harvest of turnips. This guide outlines the essential steps to growing turnips successfully from seed to harvest.
Turnips (Brassica rapa) are biennial plants usually grown as annuals for their edible roots and greens. They are part of the cruciferous vegetable family, which also includes cabbage, broccoli, and kale. Turnips are prized for their sweet, mild flavor and can be eaten raw, cooked, or pickled. Their greens are also edible and nutritious, making them an excellent addition to salads and other dishes.
There are numerous varieties of turnips, but some of the best options for growing in Wisconsin include:
Choosing the right variety for your needs will depend on your taste preferences and intended use.
The key to successfully growing turnips in Wisconsin lies in timing. Turnips thrive in cooler temperatures, making spring and fall the best planting seasons. In Wisconsin, you can plant turnip seeds:
Spring Planting: Sow seeds directly into the ground when soil temperatures reach 45°F (7°C), typically between late April and early May. This will allow for a summer harvest.
Fall Planting: For a fall harvest, plant seeds from mid-July to early August. Turnips can often be harvested well into the fall before the ground freezes.
Proper soil preparation is crucial for growing healthy turnips. Follow these steps to prepare your garden bed:
Select a location that receives full sun (at least six hours of sunlight daily). Turnips grow best in well-drained soil with good airflow around the plants.
Consider conducting a soil test to determine pH levels and nutrient composition. Turnips prefer slightly acidic to neutral soil (pH 6.0 – 7.0).
Incorporate organic matter such as compost or well-rotted manure into the soil to improve fertility and drainage. If your soil is heavy clay, consider adding sand or peat moss to enhance drainage.
Loosen the top 12 inches of soil with a garden tiller or hoe to create a fine seedbed. Remove any rocks or debris that may hinder root growth.
Once your garden bed is prepared, it’s time to sow your seeds.
Plant turnip seeds about 1/2 inch deep, spacing them 2-4 inches apart in rows that are about 12-18 inches apart. For a more intensive approach, you can plant them closer together; just be sure to thin them out later.
After planting, gently water the area to moisten the soil without washing away the seeds. Keep the soil consistently moist until germination occurs, which typically takes about 7-10 days.
Once your turnips begin to grow, they will require consistent care.
Once seedlings have reached about 2-3 inches tall, thin them out by removing weaker plants so that remaining plants are spaced 4-6 inches apart. This allows enough room for the roots to develop properly without competing for nutrients.
Turnips need regular moisture throughout their growth period. Aim for about one inch of water per week through rainfall or supplemental watering. Be careful not to overwater; soggy soil can lead to rot.
A balanced fertilizer with equal parts nitrogen (N), phosphorus (P), and potassium (K) is ideal for turnip growth. Apply it when seedlings are about four weeks old according to package instructions. Avoid excessive nitrogen as it may encourage leafy growth at the expense of root development.
Keep an eye out for common pests like aphids, flea beetles, and cabbage worms. Use row covers initially if necessary to deter insects while your seedlings establish themselves.
Regularly inspect plants for signs of disease such as downy mildew or black rot; maintaining good air circulation by proper spacing can help prevent these issues.
Timing is essential when harvesting turnips; pulling them at just the right moment will ensure optimal flavor and tenderness.
Turnips can be harvested when they reach about 2-4 inches in diameter; this typically occurs around 30-60 days after sowing, depending on the variety and growing conditions.
Check frequently during this period; if left too long in the ground, they may become woody or bitter.
Use a garden fork or shovel to gently lift turnips from the ground without damaging them. Brush off excess soil but avoid washing them prior to storage as moisture can lead to spoilage.
Turnips store well if handled correctly:
For immediate use after harvesting, store turnips in a cool place inside your home or refrigerator where temperatures remain consistent at around 32°F (0°C).
To store turnips long-term:
1. Remove greens by cutting them off (this prevents moisture loss).
2. Place unwashed bulbs in perforated plastic bags or wrap them loosely in newspaper.
3. Store them in a cool basement or root cellar with high humidity.
Growing turnips in Wisconsin offers an excellent opportunity for home gardeners to enjoy this versatile vegetable throughout different seasons of the year.
